- WATER-HEATER.

Specification of Letters Patent.

Patented Nov. 25, 1913.

T 0 all whom it may concern:

Be it known that we, JOHN O. VAN Bos- KOR and ERNEST MEIER, citizens of the United States, residing at Dwight, in the county of Livingston, State of Illinois, have invented a new and useful Water-Heater, of which the following is a specification.

The device forming the subject matter of this application is a water heater, adapted to constitute a part of a boiler of any sort, the device being so constructed that the products of combustion passing lnto the smoke box, will effect a heating of the Water before the same enters the boiler...

The invention aims to provide a structure which will not only heat the water, in the smoke box, before the water enters the boiler, but, as well, to trap and remove sediment, before the ,water enters the boiler.

It is within the scope of the invention to improve generally and to enhance the utility of, devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing :Figure 1 shows in top plan, a boiler equipped with the device constituting the subject matter of this applica tion, parts being broken away; Fig. 2 is a side elevation of the structure shown in Fig. 1; Fig. 3 is a transverse section through the smoke box; Fig. 4 is a longitudinal section through the smoke box.

In the drawings, the numeral 1 indicates the shell of a boiler, the numeral 2 denoting the boiler head and the numeral 3 indicating the smoke box.

A stack is shown at 4 and a flue sheet shown at 5, the fiues being indicated at 6.

The injector is shown at 7. A pipe 8 lies outside of the boiler shell 1 and communicates with the injector 7. Interposed in the pipe 8 is a check valve 9 which closes toward the injector 7.

Located outside of the boiler shell 8 is a pipe 10 in which is interposed a hand valve 11. The rear end of the pipe 10 communicates with the water space of the boiler.

the coil 12 is connected as indicated at 15 to the pipe 8 and the end of the forward convolution of the coil is connected as indicated at 16 to the pipe 10.

The outer forward convolution of the coil 12 is denoted specifically by the numeral 17, and interposed in the convolution 17 as shown to best advantage in Fig. 3 is a mud drum 18. The drum 18 comprises a reduced neck 19 having flanges 20 which are secured to the shell 1, the lower end of the mud drum 18 being tapered as indicated at 21. The tapered lower end of the mud drum 18 communicates with a pipe 22 which extends downwardly through the bottom of the boiler shell 1. In the pipe 22 and outside of the shell 1 is a valve 25. VThe neck 19 carries a tube 26, the inner end of which projects toward the longitudinal axis of the mud drum. the outer end of the tube 26 entering the extremity of the outer convolutions 17 of the coil. The tube 26, constitutes, to all intent and purposes, a part of the outer convolution 17 of the coil 12.

In practical operation water is delivered by the injector 7 into the pipe 8, the water passing through the check valve 9 and entering the rear convolution of the coil 12 by way of the connection 15. The water is thus disposed immediately in advance of the flue sheet 5, and, as the water passes through the coil 12, the Water is heated and products of combustion which pass out of the fines 6 into the smoke box 3 and thence pass out of the boiler shell 1 through the stack 4:. The water traverses one convolution after another of the coil and ultimately enters the pipe 10, by way of the outermost convolution 17 of the coil. By means of the pipe 10, the water, in a heated condition, is discharged into the water space of the boiler. The check valve 9, opening away from the injector 9, serves to prevent the boiler pressure from acting as a back pressure against the inj ector 7. In this connection, it is to be noted that the coil 12 at all times stands full of most convolution 17 of the coil 12, the waterpasses across the mud drum 18.. Any sediment in the water will be. received by the mud drum and the drum may bedrained off by opening the valve 251 Owing to thefact that. the tube 26 is provided, the mud and. sediment in the drum 1 8 is prevented: from foaming up into the convolution. 17 and then passing: by way of the pipe 10 into the boiler. All of the convolutionsof the coil- 12 may be drained; by opening thecocks 14.

The device herein disclosed is of simple form, but, it is so constructed that a, great saving of fuel will: be eifective, the products of, combustion being rendered effective, to heat the water, before the same enters the boiler;v All foreign. matter in the-water; will bBzI'fiIIlOVGCl and trapped by the-mud; drum 18-.

Referring to Fig. 3' it will be noted that two of the connections 15 are shown. T his; construction permits the; device to be useduponengines which employ twoinjectors.

Having thus described. the invention, what is. claimed is In. a'vdevice ofthe class described, a boiler including;- a shell, flue-sheet defining asmoke. box in the, boiler, and a stack. cont municating with the smoke box; a single ;helical coil of pipe in the smoke box, the *rear convolution of the coil being located close to. the flue sheet, the end of the rear convolution of the coil being extended out- ;si'd'e of the boiler; a source of water supply communicating with said end of the rea-rconvo'lut'ion of the coil; a mud drum secured directly to the top of the shell in advance of %the stack and acting as a deflector to facilitate: the progress of theproducts of combus- 1 tion through the stack; a pipe leading from the bottom of the mud drum through the shelli'; and a; valve in said pipe; the forward iconvolution of av coil consisting of two axially alined portions, one of which port'ionsi at its outer end communicates with the water space of the boiler, the other end of which enters the mud drum and protrudes inwardly beyond the inner face of the mud drum to form ananti-foaming nozzle, the jotherof said portions of the forward convolution of the coil entering. the mud drum and terminating at its inner end substantially flush with the inner face of the mud drum. and; opposite to the anti-foaming nozzle.

In testimony that we claim the foregoing as our own, we have hereto afiix'cd our signatures in, the presence of two witnesses.
